What is the maximum exposure rate for modern fluoroscopy equipped with automatic brightness control (ABC)?

The maximum exposure rate for modern fluoroscopy equipped with automatic brightness control (ABC) is 5 rads/min. Automatic brightness control is a feature designed to optimize the brightness of the fluoroscopic image while minimizing patient dose. The standards set forth by the American College of Radiology and the Radiological Society of North America provide guidelines indicating that for fluoroscopy systems utilizing ABC, the maximum exposure rate should not exceed 5 rads per minute. This is important in ensuring patient safety by limiting unnecessary radiation exposure during procedures.

Understanding this limit is crucial for healthcare professionals using fluoroscopy, as it helps in maintaining compliance with safety regulations and promoting effective, risk-minimized patient care.
